IMPROVEMENT IN CAR-A'XLE LUBRIQATQRS.

Specification forming part of Letters Patent No. 190,272, dated May 1, 1877; application filed March 3, 1877.

yTo all whom 'it may concern:

Beit known that we, JOHN W. BoLLMxN and JOHN G. ERNST, both ofthe city of Baltimore and State of Maryland, haveinvent-ed certain Improvements in Oar-Axle Lubricators, of which the following is a specitication; and we do hereby declare that in the same is contained a full, clear, and exact description of our said invention, reference being had to the accompanying drawing, and to the letters 4of reference marked thereon.

Figure 1 is a longitudinal section of a car-A axle box fitted with our improvedlubricating devices, which devices, together with a portion of the axle, are shown partly in section. Fig. 2'is a partly sectional plan ot' the said box and lubricating attachments. y

Similar letters of reference indicate similar parts of the invention in both figures.

A represents a car-axle box of the description ordinarily in use, and B the bearing for the axle-journal. OD is a bar fastened im-v mediately within the front opening E of the box, by means of a notched bolt or pin, a,

projecting from the inner face of the box, and a hook, b, pivoted to the bar. The hook'b is fitted to pass over the notched portion of the pin a,and thereby lock the bar and prevent its removal.4 The bar D is furnished with lugs c, extending toward the journal G,

-to which lugs the spring-supports del', for the Wicks, are riveted. The spring d, which is designed to support the wick next to the col lar 'e of the axle-journal, is curved inward at its free end in order to bring the wick in contact with the surface of the journal and lubricate it. rlhe spring d', which serves to hold the wick at the other end of the journal or `supports, and their upper ends brought into close contact with the surface of the-axlejournal. The lower ends of the wicks are allowed to lie loosely in the oil at the bottom of the box A. As it is necessary that the wicks should be rmly held within the .slots in the spring'supports, and equallyA necessary that they should not be clamped to such an extent as to stop or impede the ow of oil tothe journal, the upper and lower edges of each vslot are notched, and provided, respectively,

with a projecting lip, h, and a hinged lock, i, between which the wickis secured. G is a removable partition of some light material, placed in thebox A with its lower edge resting upon a projection, k, on the bar D, and its upper edge sustained by the edge ofthe opening E, or by a lugcast or secured to the top inner surface of the box. partition G in the box A,\as shown, is to prevent the oil contained in the boxl from dashing against the coverof the openingE, and escaping through the imperfect joint between the said cover and the face of the box. H is the supply-tube, the upper end of which is slightly below the opening through which the axle is inserted to the box. By locating the oil-tube as described, it is impossible to overcharge the box with oil', and a source of great waste is thereby removed.

Our improved oiling devices are found to prevent the heating of car-axles, and are applicable, with slight modification in size and shape, to boxes now in use.

lThe difference between the supporting-arms for the wicks herein claimed and others in use is apparent, asinV our invention they are not rigid, and are of unequal lengths, holding the wicks so as to afford greater lubricatingsurface. We are aware that it is not new to hold wicks against the journalfor the pur- OFFICE,

rlhe object of placing they pose of lubricating the same, and, therefore, do not claim, broadly, devices for elfecting this result; but,

Having described our invention, we claim as our invention- 1. In combination with a car-axle box, spring supporting-arms for holding the Wicks, the said arms being of 'unequal lengths, as described, whereby the wicks are held against different parts ofthe journal, substantially as and for the purpose specified.

2. Spring-arms of unequal lengths for holding the Wicks, combined with a removable bar, forming the base of the said arms, and suitable locking devices for securing the said bar to the axle-box', substantially as described.

' 3. Spring-arms of unequal lengths 'for sup-
